How to Concatenate Strings in Array in Rust - Step by Step Examples

How to Concatenate Strings in Array in Rust ?

Answer

To concatenate strings in an array in Rust, you can use methods like `join` or a loop to iterate through the array and concatenate each element.

✐ Examples

1 Concatenate Strings in Array with join Method

In this example,

We create a vector `words` with strings.
We use the `join` method to concatenate strings in the array with a space separator.
We print the concatenated string.

Rust Program

fn main() {
    let words = vec!["Hello", "World", "!"];
    let concatenated = words.join(" ");
    println!("Concatenated String: {}", concatenated);
}

Output

Concatenated String: Hello World !

2 Concatenate Strings in Array with Loop

In this example,

We create an array `words` with strings.
We initialize an empty string `concatenated`.
We use a for loop to iterate through the array and concatenate each element to `concatenated`.
We print the concatenated string.

Rust Program

fn main() {
    let words = ["Hello", "World", "!"];
    let mut concatenated = String::new();
    for word in &words {
        concatenated.push_str(word);
        concatenated.push(' ');
    }
    println!("Concatenated String: {}", concatenated.trim());
}

Output

Concatenated String: Hello World !
